I’d like to hope and think that the only reason you’re unrooting your Droid Eris is because you have a problem with it and you need to return it to Verizon for a replacement. The custom 2.1 and 2.2 ROMs (i.e. KaosFroyo) available for the Eris are far superior to the stock firmware. Anyway, here is a simple step-by-step guide to unroot your Droid Eris, making it safe to return to Verizon!

Download and run RUU

Running RUU (Rom Upgrade Utility) is your way of getting your Eris back to stock. There are other methods of unrooting, but I feel after doing all my research that RUU is the safest, easiest route to go; however, RUU requires you to be in a Windows machine. If you’re on a Mac, you can always run Windows virtually using software like Parallels or VMWare Fusion.

Getting a version error?

There are reports of people getting a version error when running RUU; don’t panic. If you are, you need to first run jcase’s “Flash any RUU.” You will need to run ADB commands; therefore, if you do not have the Android SDK installed, you will need it.
